Specicaton of Letters Patent;

Patented Nov. '7, 1911.

Application led January 24, 1910. Serial No. 539,698.

To all whom it may concern:

Be it known that I, JAMES H. BANKS, a citizen of the United States,residing at York, in the county of York and State of Nebraska, haveinvented certain new and useful Improvements in Photograph-Printographs;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to an improved photographic contact printingmachine for use wit-h either artificial or daylight.

The object of the invention is to provide a simply constructed rapidlyoperable photo printing machine which is especially applicable forprinting photographic postcards which necessitate a rapid method ofproducing them to render them protable.

Vith the foregoing and other objects in view, the invention consists ofcertain novel features of construction7 combination and arrangement ofparts, as will be more fully described and particularly pointed out inthe appended claims.

In the accompanying drawings: Figure 1 is a rear elevation of thisimproved machine with the parts in operative position ready for printinga sensitized paper or card. Fig. 9. is a similar view of the exposureframe. Fig. 3 is a central longitudinal vertical section of the machinewith the part-s shown in inoperative position. Fig. 4 is a similar viewwith the parts in operative position. Fig. is a horizontal section takenon the line 55 of Fig. 4. Fig. 6 is a similar view taken on the line 6 6of Fig. 4. Fig. 7 is a detail horizontal sectional view through theexposure frame. Fig. 8 is an enlarged detail horizontal sectional viewthrough the exposure frame taken on the line 8-8 of Fig. 4. Fig. 9 is adetail perspective View of one of the automobile reseating gages. Fig.10 is a similar view of the other gage.

In the embodiment illustrated a main printing frame 1 is shown,preferably composed of two hingedly connected sections 2 and 3, themember 2 constituting a fixed frame adapted to be mounted within awindow in a room which has been darkened or the windows covered withorange or ruby colored paper. This member 2 preferably comprises a plate4 of any suitable material having an opening 5 of any desired shape andsize, the walls of which are spaced at suitable distances from the edgesof the plateto permit the plate to be secured by any suitable fasteningmeans to the window frame or other support. A frame 6 extends around thetop and sides of the opening 5 and the inner faces of the side members 7and 8 of said frame 6 are inclined downwardly and forwardly toward theirlower ends whereby the upper portion of the frame is rendered muchthicker than the lower portion for a purpose to be described.

The member 3, which is hinged at one side to the outside edge of one ofthe side members of the frame 6, will by reason of the inclined faces ofthe frame members 7 and S against which the inner face of the member 8contacts when in operative position be caused to tilt rearwardly at thetop to permit the paper or card containing the exposed print to dropbackward on the platen when said platen is opened without vnecessitatingremoval of said card by hand as will be hereinafter described. This mem'ber 3 has a large opening 9 therein in the lower portion of which ismounted a ground y glass light diuser 10 and a ruby or orange ycoloredtransparent pane 11 is arranged in Isaid opening 9 above the lightdiffuser 10 to .afford suflicient light to enable the operator to see tomanipulate the cards without injuriously affecting them. The side wallsof the opening 9 are grooved longitudinally in front of the plates 10and 11 to receive a `plain glass vignetting plate 12, which is slidablein said grooves in front of the ground glass plate 11. The hinged framemember 3 is provided at opposite sides at the rear of said glass plateswith longitudinally disposed guides here shown in the form of grooves orrecesses 13 and 14 in which an exposure frame 15 is mounted to slide.This frame 15 is limited in its upward movement by the upper end of themember 3 which extends laterally in the path of the frame 15 and thedownward movement of said frame 15 is limited by detachable stops as 16arranged at the lower ends of the grooves 13 and 14. These stops as 16may be removed to permit the insertion and removal of the exposureframe. This exposure frame 15 may be made in any suitable or desiredsize to receive negatives of varying sizes and as shown is provided atthe front thereof with an inwardly extending flange 17 arranged aroundthe opening in the frame and against which the edges of the negative as18 are designed to contact when in operative position. The lower edge ofthe opening in the frame 15 is preferably provided with a seat 19 toreceive the lower edge of the negative, said seat being preferablyformed by a strip 2O spaced from the flange 17 at the bottom of theopening a suflicient distance to receive the negative and to hold itagainst lateral movement.

An automatic negative lock is shown arranged at the upper end of theframe 15 and comprises a spring catch 21 which is secured to the upperend of the frame 15 and the free'resilient end thereof projects into thepath of the upper edge of the negative and is designed to springbackward against the rear face thereof to hold said negative firmly inoperative position. To release the negative the free end of this lock ispressed upward thereby disengaging it from the negative which is movedrearwardly by an ejector 22 of any suitable or desired construction, theform here shown comprising a wire member 23 having one end coiled andsecured to the lower face of the upper portion of the frame 15 in arecess 24 formed in the said frame. The free end of this wire 23 has adepending tongue 25 which normally engages the outer face of the upperedge of the negative, the spring tension of the coil of said member 23being exerted to force the negative outward when disengaged from thelock 21. A platen 26 is hinged at its lower edge to the bottom wall ofthe opening in the frame 15 to open downwardly and is preferablyprovided on its outer face with automatic opening means. The means hereshown for opening the platen comprise a coiled spring 27 secured tol thelower part of the frame l5 and having a loop 28 engaged with a keeper 29secured to the rear face of the platen, said loop being slidablyconnected with said keeper to permit the ready closing of the platen.This spring tension loop operates normally to pull the platen backwardinto open position.

An automatically receding card or paper gage is mounted on the platenand as here shown comprises two members 30 and 31 mounted on the rearface of the platen with the arms thereof projecting through slots as 32arranged near the lower end of the platen and at both sides thereof, theslots at the lower end being spaced laterally. The member 30 ispreferably constructed as shown in detail in Fig. 10 from a piece ofspring wire bent intermediately of its ends to form a loop 33, the freeends of which are bent laterally in opposite directions to each otherwith their terminals bent ont at right angles to form card engagingmembers 34 and 35 which project through the slot-s at the lower end ofthe platen and extend beyond the inner face of said platen in positionto receive the sensitized card or paper on which the print is to bemade. A screw-threaded stud 36 extends laterally from the rear face ofthe platen preferably at a point about the center thereof and the loop33 of the member 30 extends over this stud and is held in adjustedposition thereon by a milled nut 37, said loop being adjustable on thestud to move the card engaging arms or lingers 34 and 35 into anydesired position to receive cards of different widths or sizes. The bentor doubled end of the loop 33 is preferably bent outwardly at rightangles to form a finger grip 38 for adjusting the gage fingers 34 and35. The other gage member 31 is preferably constructed as shown indetail in Fig. 9 from a piece of spring wire having one end thereof bentto form a loop 39, the doubled end of said loop being bent at rightangles to form a finger grip 40 for operating said gage t) move it intothe desired position, the loop being designed to fit over the stud 36and held in position thereon by the nut 37. This wire member 31 has anoifset 41 formed intermediately of its ends which operates in the slot32 at the side of the platen and the free end thereof is bent at rightangles to form a card engaging finger 42, which projects through theside slot of the platen and is adjustable laterally to hold the card tobe printed against side movement. These gage members being constructedof spring wire are resilient and when coming in contact with thenegative move inwardly in the slots in which they are mounted and permitthe card or paper carried by the platen to come in close conn tact withthe negative whereby a perfect print is produced. 7

An impression bar 43 is adjustably secured at its opposite ends to theside members of the frame member 3 preferably by means of screw-threadedstuds 44 and 45 which extend laterally from said frame member 3 throughapertures formed in the ends thereof to provide for the lateraladjustment of said bar to adapt the frame to lit negatives of differentthickness. Mounted on the lower face of this bar 43 are twolongitudinally spaced rollers 46 and 47 which are fastened to bearagainst the rear face of the platen when the exposure frame 15 is moveddownwardly thereby automatically closing the platen. This pressure bar43 is preferably constructed as shown in detail in Fig. 10 comprising aroller carrying member 48 through which the studs 44 and 45 pass.

A curved plate spring 49 is secured to the upper face of the member 48preferably midway the ends thereof, the free ends thereof being designedto bear against a plate or bar 50 which is also mounted on the studs 44and 45 and is held in adjusted position by the nuts on said studs. Thisspring 49` provides for the lateral yielding of the roller carryingmember 48 to permit the exposure frame topass rapidly thereunder. Theupper edges of the bar 48 and plate 50 are preferably recessed asshown'- at 51 to receive the keeper on the platen when the platen isopened downwardly to permit said platen to open to its full extent.

A hook member 52 is secured to the lower edge of the exposure frame 15with which an adjustable telescoping pedal rod` 53 is detachablyconnected.- preferably by passing said hook 52 through an aperture inoneend of said rod. This rod is preferably composed of two telescopingsections 54 and 55 adjustably connected by any suitable means. The otherendA of the rod 53 is connected with a pedal 56 preferably at a pointintermediately of its ends, one end of said pedal being pivotallymounted on a suitable support and the free end thereof being connectedwith one end of a coil spring 57. The other end of this coil spring 57is connected with the lower end of the mainframe 1 as is shown clearlyin Figs. 1 and 2, and when the pedal is depressed the exposure frame ismoved downwardly against thetension of the spring 57 which exerts itstension to return the frame into inoperative position when the pedal isreleased. The telescoping pedal rod it will readily be seen is easilyadjusted to adapt the machine for use on windows of varying heights orfor use by operators of different heights.

A removable table or cabinet 58 is preferably mounted on the main frame1 by means of hooks which are detachably connected with eyes at oppositesides of the frame 1 to provide for the removal of said table or cabinetwhen desired. This table or cabinet is preferably provided below the topthereof with two drawers 59 and 60 for containing exposed and unexposedcards or paper which are thus held in convenient position for the use ofthe operator.

In the operation of this improved machine the negative is first placedin the exposure frame 15 with the film side toward the operator andpressed therein until the automatic locking device 21 snaps over theupper end of the negative. The sensitized card or paper is then placedon the platen resting against the receding gages which have beenpreviously adjusted to the desired position. These receding gages whencoming in contact with the negative move backwardly and allow the cardor paper to make a complete contact and they render it possible todispose the negative and the card or paper in vertical position. Thepedal is then depressed which causes the exposure frame to movedownwardly and the rollers 46 and 47 bearing on the platen to close itand the further descent of the frame 15 exposes the negative to thewhite light which is diused through the ground glass light diffuser. Thedensity of the negative, the volume of lightv and the number of tissuesin the vignetting plate govern the length of time necessary to make theexposure. lVhen the pedal is released, the exposurel frame automaticallyrises under the action of the spring 57 and at the instant the rubycolored plate 10 is reached the platen opens automatically allowing avolume of ruby light to fall upon the table and platenaiiordingsuflicient light to enable the operator to manipulate the cards which heis printing. When the platen opens the operator removes the printed cardwith his left hand at the same time placing an unexposed card intoposition with the right hand whereby the printing of the cards may berapidly accomplished, a hundred or more exposures being made in aboutfive minutes depending upon the skill of the operator,the volume oflight and the density of the negatives or vignetting. When the requirednumber of prints have been made from one negative the operator releasesthe negative by pressing upward on the auto- `matic locking device 21which holds the negative in place and the automatic ejector jwill thenpress the negative outward and cause it to fall back into the hand ofthe operator ready for removal.

The formation of the main frame of hinged members provides for theopening of the machine to permit the adjusting of the vignetting plateinto position.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention, as defined in theappended claims.
